Senior Propulsion Engineer - Engines

About the role

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! This role is part of the Blue Origin Engines business unit, where our focus is the design, development, manufacturing, and testing of engines and propulsion systems. Built for multiple uses, our family of engines is powering the next generation of rockets for commercial, civil, national security, and human spaceflight. As part of a small group of engineers, you will serve as the technical integrator for a LOX/LNG booster engine. You will sit at the intersection of every technical discipline on the program, owning the systems architecture, driving requirements from top-level customer needs down through subsystems, and ensuring that every design decision rolls up into a system that meets its performance, reliability, and operability goals. This is a role with real ownership and real influence, on a team that moves fast, dives deep, and does not settle for good enough.

Don’t meet all desired requirements? Studies have shown that some people are less likely to apply to jobs unless they meet every single desired qualification. At Blue Origin, we are dedicated to building an authentic workplace, so if you’re excited about this role but your past experience doesn’t align perfectly with every desired qualification in the job description, we encourage you to apply anyway. You may be just the right candidate for this or other roles.

Responsibilities

• Own the engine-level systems architecture, ensuring design decisions made at the subsystem level are coherent, traceable, and optimized for the system as a whole
• Develop, decompose, and allocate requirements across subsystems, maintaining clear traceability and a credible path to verification for every requirement
• Define and control all key interfaces between engine subsystems and between the engine and vehicle, resolving conflicts before they become integration problems
• Lead engine-level trade studies with analytical rigor, driving clear recommendations that advance the program rather than cataloguing options
• Actively engage with test data, anomaly investigations, and design iterations to identify
